'BRICIK-MOLD.

SPECIFICATION forming part of Letters Patent No. 414,918, dated November12, 1889.

Application filed March 12, 1889. Serial No. 302,947. (No model.)

T at whom it may concern.-

Be it known that I, ALEXANDER PAUL, of Meyersdale, in the 'county ofSomerset and State of Pennsylvania, have invented a new and ImprovedBrick-Press Box, of which the following is a full, clear, and exactdescription.

' The invention relates to brick-pressing machines; and its object is toprovide a new and improved press-box which is simple and durableinconstruction and so arranged as to take up all wear.

The invention consists in the novel construction and arrangement ofparts of the brick-press box, as hereinafter described'and claimed.

Reference is to be had tothe accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan View of theimprovement. Fig. 2 is a side elevation ofthe same. Fig. 3 is a sectional side elevation of the same on the line00 a: of Fig. 1. Fig. 4c is an end view of the same, and Fig. 5 is aperspective view the sides B and C.

of one of the ends.

The improved brick-press box A comprises the tWo sides B and O and theends Dand E, fastened by the bolts F to the said sides B and O. Saidbolts F pass through corresponding apertures formed in the sides andends, as is plainly shown in the drawings. Each of the ends D and E *isprovided with transversely-extending lugs or projections D or E,extending through the entire height of each end and fitting intocorresponding grooves B and C, respectively, in the sides B and 0.

Instead of fastening the sides to the ends D and E by means of the boltsabove described,

I may employ wedges G, passing through apertures H, formed in the lugsH,extending from the ends of the projections D and E, above described,and plainly shown in Fig. 5. Said lugs H project through aperturesformed in (SeeFig. 2.) The wedges G project at both ends of the lugs Hand pass into grooves I, formed on the outer surfaces of the sides B andO. Instead of employing either the bolts F or the wedges G, as abovedescribed, for fastening the sides and ends together, Imay employ both,as is plainly illustrated in the drawings.

At the ends of the projections D and E in the grooves B and O are placedstrips or usual ears N for fastening the box on the bedplate of thebrick-pressing machine.

The sides and ends are preferably made of cast-iron, steel, or othermetal, and if made of cast-iron the faces of the sides and ends are tobe chilled and the several parts are to be fastened together by bolts F.If the sides and ends are made of steel, they are put together witheither bolts F or wedges K and keys G, as before described.

The liners J and the wedges K are removed when the sides and ends areworn out, and may be refitted by having their faces either planed orground off and thinner additional liners or keys put in, so the box willbe as good as new. The wedges K serve to hold the ends of the box tightin the grooves in the sides, and also to keep the strain 01f the bolts.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A brick-press box comprising two-sides vertically grooved at theirends, two end pieces having tenons on their ends of less depth and widththan said grooves, the securing-bolts, the strips J L, and the wedges Kin the vertical end grooves between strips J L, substantially as setforth.

2. A brick-press box comprising the sides B 0, having vertical endgrooves O and longi-' tudinal grooves I, the ends D E, each providedwith a tenon, a transversely-apertured lug I-I, extending therefromthrough the sides and grooves I, a wedge in said grooves and passingthrough said apertures, the bolts F, passing through the sides and endsabove the lugs H, the strips J L, and the intermediate wedges K,substantially as set forth.
